Description
Technical field
The present invention relates to a kind of safety protection apparatus for elevator, belong to the elevator field.
Background technology
Along with the development of society, increasing people has moved into building from one-storey house, because the height of building is higher, usually can be equipped with elevator.Because elevator of the prior art all is to adopt the rope car that plays, and controls the upper and lower of elevator by motor.Owing to can rub between rope and the pulley, in use unavoidably accident can appear, in case the fracture of the rope of elevator is easy to cause the Personal Risk so.Therefore be widely used because rope elevator cost is low, yet the rate of meeting accident of rope elevator also obviously increases in widespread use, the rope elevator is easy to occur the terraced phenomenon of card even pendant occurs terraced when meeting with suddenly power failure, although the rope elevator has been installed falling proof device at present, what these falling proof devices had when running into accident or having a power failure suddenly can't use.
Summary of the invention
The object of the invention is to, a kind of safety protection apparatus for elevator is provided, it can prevent effectively that elevator from the terraced accident of pendant occuring, personnel's safety in the protection elevator, and the present invention need not electricity consumption, even power down mode also can work.
Technical scheme of the present invention: a kind of safety protection apparatus for elevator, comprise dash plate, recoil spring and spring perch, two symmetrical faces of the bottom of elevator are provided with symmetrical dash plate, the top of dash plate is hinged by the inwall of hinge and elevator, be provided with recoil spring between the inwall of dash plate and elevator, the two ends of recoil spring are separately fixed on the spring perch of being located on dash plate and the elevator; Be provided with car in the elevator, the bottom of car is provided with taper deceleration piece.When the rope fracture of elevator, car can descend rapidly, by dash plate gradually impulsive force that car is downward eliminate, finally make car stop to fall.
In the aforesaid safety protection apparatus for elevator, the recoil spring between dash plate and the elevator inside is matrix type and distributes.Adopting this distribution mode can be that spring stress prevents that evenly the situation that discontinuity tilts dash plate from occuring.
In the aforesaid safety protection apparatus for elevator, the recoil spring between dash plate and the elevator inside from top to bottom length increases gradually.Adopting this mode is for gradually that car is downward impulsive force eliminates, and prevents that suddenly deceleration of car from causing injury to personnel in the elevator.
In the aforesaid safety protection apparatus for elevator, the plate face of dash plate is provided with speed-reducing rubber piece A.It is for increasing friction force that the speed-reducing rubber piece is set.
In the aforesaid safety protection apparatus for elevator, described speed-reducing rubber piece A is shaped as triangle or semisphere.
In the aforesaid safety protection apparatus for elevator, taper deceleration piece adopts the alloy material manufacturing to form.Taper deceleration piece adopts the reason of alloy material to be, alloy material is not yielding, and the taper deceleration piece that this material making is set in the car bottom can prevent that car from deforming.
In the aforesaid safety protection apparatus for elevator, the conical surface of taper deceleration piece is provided with speed-reducing rubber piece B.It is for increasing friction force that the speed-reducing rubber piece is set.
In the aforesaid safety protection apparatus for elevator, speed-reducing rubber piece B is shaped as triangle or semisphere.
Compared with prior art, because the present invention is provided with dash plate in the bottom of elevator, and between dash plate and elevator, be provided with recoil spring, when the terraced accident of pendant occurs when, the car downward impulsive force when contacting with dash plate that falls rapidly can be cushioned plate and weaken gradually, until car stops to fall.Because lower anti-recoil spring is longer than the recoil spring of top, dash plate increases gradually to the resistance that car makes progress, and car is steadily slowed down, and effectively protects the safety of personnel in the car.Because the present invention does not need the auxiliary of electrical equipment therefore to need not power supply, even can work when having a power failure yet.
Description of drawings
Fig. 1 is integral structure scheme drawing of the present invention;
Fig. 2 is that speed-reducing rubber piece A and speed-reducing rubber piece B are hemispheric structural representation.
Being labeled as in the accompanying drawing: 1-dash plate, 2-recoil spring, 3-spring perch, 4-elevator, 5-car, 6-taper deceleration piece, 7-speed-reducing rubber piece A, 8-speed-reducing rubber piece B.
The specific embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
Embodiments of the invention 1: as shown in Figure 1, a kind of safety protection apparatus for elevator, comprise dash plate 1, recoil spring 2 and spring perch 3, two symmetrical faces of the bottom of elevator 4 are provided with symmetrical dash plate 1, the top of dash plate 1 is hinged by the inwall of hinge and elevator 4, be provided with recoil spring 2 between the inwall of dash plate 1 and elevator 4, the two ends of recoil spring 2 are separately fixed on the spring perch 3 of being located on dash plate 1 and the elevator 4; Be provided with car 5 in the elevator 4, the bottom of car 5 is provided with taper deceleration piece 6.Recoil spring 2 between dash plate 1 and elevator 4 inside is matrix type and distributes.Recoil spring 2 between dash plate 1 and elevator 4 inside from top to bottom length increases gradually.
The plate face of dash plate 1 is provided with speed-reducing rubber piece A7.Described speed-reducing rubber piece A7 is shaped as triangle.
Embodiments of the invention 2: as shown in Figure 1, a kind of safety protection apparatus for elevator, comprise dash plate 1, recoil spring 2 and spring perch 3, two symmetrical faces of the bottom of elevator 4 are provided with symmetrical dash plate 1, the top of dash plate 1 is hinged by the inwall of hinge and elevator 4, be provided with recoil spring 2 between the inwall of dash plate 1 and elevator 4, the two ends of recoil spring 2 are separately fixed on the spring perch 3 of being located on dash plate 1 and the elevator 4; Be provided with car 5 in the elevator 4, the bottom of car 5 is provided with taper deceleration piece 6.Recoil spring 2 between dash plate 1 and elevator 4 inside is matrix type and distributes.Recoil spring 2 between dash plate 1 and elevator 4 inside from top to bottom length increases gradually.
